Many are confused with the connection.Generally Rx goes to Tx & Tx goes to Rx..This is the rule.But the GSM board I',ve used here has a MAX232 IC & T1IN/R1OUT of 232 IC is printed as TX/RX & not that of GSM SIM300.
If this is not working for you simply swap the connections.The connections shown in video is correct when you use a NSK GSM board.
Always ensure that
Rx of Arduino (pin 0) goes to pin 11 (T1 IN) of MAX232 IC &
Tx of Arduino ( pin 1) goes to pin 12 (R1 OUT) of MAX232 IC.
No matter whether you've or not the 232 IC ,as we are using TTL logic signals

In this video we are building a Temperature and humidity monitor, using an Arduino Mega, an LCD Display Shield with a DHT11 sensor. If you have a DHT22 sensor, the wiring is exactly the same.
What will you need:
1. An Arduino board (Mega, Uno, Due, Nano, Micro, etc. )
2. An LCD screen: http://www.ekitszone.com/lcd1602-keypad-shield (this is the one that I use because I had bought it long time ago)
or this one: http://www.banggood.com/Keypad-Shield-Blue-Backlight-For-Arduino-Robot-LCD-1602-Board-p-79326.html?p=DQ30066511122014069J (this is one is a lot cheaper)
3. The DHT11 sensor which can be bought from here:
http://www.banggood.com/DHT11-Digital-Temperature-Relative-Humidity-Sensor-Module-With-Cable-p-933486.html?p=DQ30066511122014069J
Library for the DHT11 sensor: https://github.com/adafruit/DHT-sensor-library

For this we are using a Zigbee based network for doctor to patient communication in the hospital and even to communicate and indicate the status of the patient through SMS. This way of communication is actually done with Zigbee network topology and with the GSM network. Each patient will be given this module and with the help of this module the patient health condition is monitored and if there is any change in the condition of the heath then it immediately sends that changed data through Zigbee to the local system where the main module is connected to the computer to maintain the status of the patient. The same information is transfer as message to GSM to the corresponding or the relevant person. In this we check the patient's health condition by monitoring the heart beat. The heart beat is monitored with the pulse rate of the body. The high intensity light sensor senses the expansion and contraction of the heart with the hel... less

This is my Arduino quadcopter. It uses one Arduino Uno to control the motors based on information received on the Xbee module. Controls are sent from the iOS device wirelessly to a laptop into Processing which then feeds them into my Arduino Base Station.

This video shows a water control system I designed and built to control multiple water tanks, solenoids, sensors, and one water pump. I used the Arduino UNO to control the conditions needed for the application and to manage IO.

Combining Arduino's with mechanical devices and machined parts is just amazing. I'm working on a project using a stepper as a "feed device" and wanted to make a video experimenting with various ways to control the Arduino Stepper as well as measuring to see just how accurate it could be!

I don't have much time so I didn't prepare a nice mash-up or a dubstep music, this is just for showing the potential of the project.
The hardware (the protoboard with the arduino and components) is made of lots of transistors for 'body signal' amplification, so the coke I touched activates the transistor (BC548B NPN). The cokes are plugged in directly to the transistor's base with an wire. Then the arduino reads the data and sends it via serial to the python script.
(I'll write a tutorial soon)

Now the temperature is far more precise, and the cola tastes far more delicious. The SD card saves all the events, temperatures and relay activity every 20 secs; this allows me to do data mining over the data, estimate consumption, efficiency, and enhance the cooling process.
